Abstract

Pasir besi yang dijadikan sebagai bahan acuan baku (standard reference material)diperoleh dari pesisir pantai selatan Kabupaten Kulon Progo, Yogyakarta dan pesisir pantai selatan Kabupaten Ende, Nusa Tenggara Timur. Metode pembuatan bahan acuan bakumeliputi metode pengambilan dan penanganan conto di lapangan, preparasi conto di laboratorium, pelabelan, analisis kimia di delapan laboratorium terhadap conto pasir besi, serta metoda pengolahan dan analisis data secara statistik. Analisis kimia di delapan laboratorium terhadap empat jenis conto pasir besi menghasilkan bahan acuan baku pasir besi dengan konsentrasi (% berat) berkisar antara 23,81% - 50,46% Fe total, 19,63% - 43,16% Fe O , 19,90% - 25,22% FeO, dan 3,74% - 7,60% TiO.
